Installing a hydraulic booster on a VAZ 2106

Cars of the classic series developed by VAZ do not particularly pamper our fellow citizens with additional equipment. Power steering was not installed as standard on the VAZ 2107; none of the rear-wheel drive models of this manufacturer can boast of such a sophistication. Additional equipment to reduce the load on the driver and facilitate control can only be installed as an option.

The power steering for the seven was specially designed and manufactured by one of AvtoVAZ’s development plants. The kit has been successfully tested and approved for use on vehicles of this model. It should be remembered that the operation of vehicles with changes made independently to the steering design is prohibited; in fact, this is a restriction on the use of non-certified equipment.

Useful functions of electric power steering on the VAZ 2106

Classic AvtoVAZ - 2106

Ten years ago, Russian drivers could not even dream of having the steering wheel equipped with any kind of reinforcing mechanism. Then proven, old-fashioned methods were used, which could not please with either the proper effect or reliability.

But life goes on, everything changes. Progress does not stand still. So, a new invention has come into the world, an achievement of the 21st century - power steering. What is it, what are its advantages and possible disadvantages, and what is the difference between the electric power steering on a VAZ 2106 and the power steering?

The process of installing power steering on a VAZ classic.

Installing power steering on a VAZ 2106 is not particularly difficult and even an inexperienced driver can handle it. Initially, you need to make sure that the power steering kit is complete and that you have all its parts in stock. The power steering kit consists of a pump, pulley, steering gear, hydraulic cylinder, as well as a pressure reservoir and hoses.

Next we move on to the actual installation. Install the pump bracket directly onto the cylinder head, and then secure the pump. Next, we change the crankshaft pulley so that it fits the pump drive. It must be remembered that the pump drive must pass through a belt and not through a chain. Then you should start changing the steering gear. At this stage you need to improve the design a little. To install the gearbox, you need to make holes on the car's dashboard.

Next, choose a place to install the expansion tank. Install the hydraulic cylinder. When installing it, you must follow the special instructions that come with the hydraulic booster .

After all these steps, we connect the system with high-pressure hoses. They should not rub against each other or other parts. We pour oil into the power steering and expansion tank, and begin bleeding the system.

A little about steering mechanisms

Power steering for 2106

Since the creation of the car, engineers from all countries and continents have been constantly puzzled by one question: how to improve its performance, how to make the car more controllable, stable and reliable? This became the impetus for the invention of such a device as power steering.

The steering wheel is the backbone of a car. You can't go anywhere without him. Even if the engine is excellent and all the parts are new, but the steering wheel loses its position, there can be no driving. That is why it is so important to give this element a significant share of your attention.

The steering mechanisms installed on the first car models, and then on the Volgas, Zaporozhets and Ladas that are more familiar to us, are called “worm-sector”. This system is based on a worm-gear pair. Starting from the 40s, and in Russia from the 60s, such a mechanism was considered obsolete and gave way to a ball screw, which showed better characteristics, was more reliable and wear-resistant.

In the 70s, a rack and pinion steering wheel was proposed. This mechanism turned out to be very technologically advanced and was in perfect harmony with front-wheel drive and the MacPherson suspension, fashionable at that time. This kit provided the car with excellent handling and stability.

Rack-and-pinion steering is still used today, and is used primarily in passenger cars, while trucks and some SUVs are still paired with ball-and-screw steering.

In the seventies, leading engineers of famous European automakers began an active search for new ideas, paying special attention to the creation of such a device as power steering. The first attempts were unsuccessful; the mechanism turned out to be unreliable, often broke down and did not give the expected effect.

After numerous experiments, tests, and tests, a solution was finally found. Today, every car owner can choose between two types of amplifiers - electric power steering, that is, electric power steering, and power steering. Let's see what the difference is between the two types of this mechanism.

Main characteristics of the hydraulic booster

Power steering, or power steering, is an integral mechanism consisting of a rotary pump coming from the crankshaft and many parts, each of which has a specific role. The hydraulic booster actively interacts with the steering mechanism and the oil distributor. The technology itself is quite complex, so we will not dwell on this issue. It is much more important to know what this mechanism provides.

The amplifier ensures more comfortable and safe movement. It is worth noting that even if the front tire is defective, the power steering allows you to maintain controllability. It is this quality that has made the hydraulic booster so popular among car owners.

Power steering system on the car

Operating functions of the power steering:

improving vehicle handling;
significant softening of shocks that were previously transmitted to the steering wheel (while driving on a bumpy road);
control over vehicle controllability in critical cases;
significant improvement in vehicle maneuverability, reduction in the number of steering turns;
creating the so-called “feeling of the track,” which is important.

It is especially good to install power steering on a VAZ. These cars themselves cannot please you with either good dynamics or powerful handling, so modernization will not hurt.

We've sorted out the advantages. Are there any disadvantages to this device? Sometimes drivers complain about insufficient reactive steering assistance. It often happens that while solving one problem, we lose in another matter. Here, too, the engineers were unable to eliminate both problems; one of them always makes itself felt.

There is inefficiency in fuel consumption in vehicles equipped with power steering. But this problem is completely solvable; it is enough to route the power steering pump not from the crankshaft of the power unit, as is usually done, but from the electric motor. In this case, everything changes: both the performance level of the mechanism and fuel consumption.

By changing the operating principle of the electric motor and the rotation frequency, you can adjust the operation of the amplifier. Such a hydraulic system is installed on Mercedes-Benz cars, which already says a lot.

Features of the electric amplifier

Electric power steering mechanism for 2106

EPS, or electric power steering, is a mechanism built not on a hydraulic principle (that is, in connection with an oil fluid), but on the basis of current pulses. A special controller ensures that the current is supplied with the required polarity and strength. The gain characteristic can be changed using a sensor.

Electric amplifiers perform the following tasks:

improved maneuverability and controllability;
ensuring operation under any temperature changes, since the mechanism does not react in any way to frost;
fuel economy.

So, we have two types of amplifiers. What is their difference?

Power steering has a simpler design and is easy to set up, but at the same time, constant maintenance of the pump is required.
The EUR is economical, which is something that the power steering cannot please.
Power steering has more power than electric power steering.

How does an electric booster work?

The electric power steering on the VAZ-2107 starts to work and creates additional torque, which reduces the force required to turn the wheels. Moreover, it begins to work simultaneously with the driver turning the steering wheel. The device is able to reduce the load required to turn the steering wheel by 5.7 times.

In other words, if you applied a force of 20 kg before installing the device, then after that only 3.5 kg will be enough for a similar action. Stages of device operation:

Using a speed sensor, a normal relationship is ensured between the gain of the device and the intensity of vehicle traffic. If the speed is low, it becomes harder to turn the steering wheel. Therefore, the control unit understands that the gain needs to be increased. Conversely, if you are moving at high speed, then you need to apply less force. Therefore, the electric power steering is not involved in steering.

Tutorial on installing power steering on a VAZ 2106.

Salam to everyone! There are already articles on this topic, but since each case is unique in its own way, I will describe in detail how it all happened. I’ll say right away that the article is not for the faint of heart and not for those whose hands do not grow from their shoulders. There are many places where non-standard situations arise: somewhere to knock, somewhere to bend, somewhere to file, and somewhere to weld. Everything needs to be done reliably, carefully thinking through every step.

It all started with a “Shniv” gearbox, which was accidentally caught at a flea market and was given away for almost nothing.

Next, I began to look for other spare parts and came across the website of the manufacturer of these same devices: “Steering Components LLC.” I’ll say a few words about this resource. Since I had not installed power steering before this incident, the support representative was at one point inundated with a barrage of my chaotic and not entirely competent, or rather not at all competent, questions. The representative withstood my onslaught with dignity and brilliantly answered each of the questions, thereby creating in me strong confidence in the seriousness of their enterprise. In the process of communication, it turned out that a ready-made “GUR FOR VAZ 2101-2107 CLASSIC” kit is currently available for purchase. This is a kit that is installed in the corresponding car without any “collective farm” (in the worst sense of the word). But since this option is too expensive for me, and I already had the Chevy-Nivovsky gearbox in stock, after clarification of all my questions, the rest of the VAZ kit was additionally ordered without, accordingly, the gearbox.

I would like to express my gratitude to the plant representatives for their contact and comprehensive assistance in installation!

In addition to the power steering kit itself, the fan, brakes, and steering wheel were modified. The fan remains the same, let's finish it a little.

You need to buy an additional Vacuum Brake Booster (VUT) from Niva, also known as the “nine-wheel” one, and you will also need a very rare part, this is the “Nivovsky” bracket for the VUT. The main brake cylinder (GTC) can also be supplied from the Niva, but I personally am not satisfied with the presence of brake hoses, so the GTZ was also supplied from the Nine.

Note from factory:

As it turned out, a small series of “classic fives” equipped with this same power steering was released. As I understand it, they did not change the standard VUT and GTZ, they simply shifted it forward by 6 mm using an adapter plate, and re-drilled the hole in the brake pedal with a shift of 6 mm (the old hole was pre-welded).

Yes, I almost forgot, the brake/clutch pedals will have to be removed, the plate at the bottom (under the gearbox) is slightly filed down and the brake pedal is bent to go around the thicker steering shaft and the gearbox housing protruding into the interior. In this regard, I don’t know what options there are, maybe some kind of Nivov pedal, in short, I “hit” it with a copper hammer and digested a nickel of the pedal itself, much like in this article.

You can also buy a steering bracket with a short shaft.

For convenience, the hood was removed, the fan was removed, the washer and antifreeze tanks were removed or moved aside, the old VUT was removed, the gearbox and pedals were removed. The clutch was also completely removed.

Power steering for VAZ 2107

The cars of the Volzhsky Automobile Plant of the classic series are not considered comfortable or as convenient as possible for movement. The main goal of the VAZ “classic” is to be an economy class car for home or work, so any options or the latest equipment systems were simply not provided for in domestic models.

A power steering wheel was not installed on the VAZ 2107: this mechanism was difficult to install in the systems of a rear-wheel drive car, and besides, such equipment significantly increased the market value of the car.

The first hydraulic boosters for the VAZ 2107 were designed and manufactured at AvtoVAZ. However, production batches could not boast of the latest equipment - power steering was sold as an additional option.

Advantages of a car with hydraulic power steering

Why do we even need additional equipment for the “seven” if the car already fully met all the requirements of its time?

Hydraulic power steering (or power steering) is an element of the vehicle’s hydraulic system, a structural part of the steering wheel. The main task of the power steering is to ease the driver’s efforts when driving a car, that is, to make steering turns easier and more accurate.

The VAZ 2107 power steering device is designed in such a way that even if it fails, the car can be driven, the steering wheel will just turn harder.

Technical inspection after installing the EUR on a VAZ 2107

Installing an electric booster is formally considered to be making changes to the design of the car and is an obstacle to undergoing maintenance without the appropriate certificates of conformity. It will not be possible to hide the fact that an ESD is installed on a VAZ 2107 - the device clearly manifests itself when checking the steering wheel play. This may become a basis for refusing to issue a document confirming the completion of a mandatory technical inspection.

To pass a technical inspection in accordance with the law, you need to find an official letter from the manufacturer about the compliance of this EUR model with the requirements for installation on a VAZ 2107. This letter (copy) must be taken with you when undergoing vehicle inspection.

Also, for maintenance, a document is required confirming the installation of the EUR at a VAZ-certified car service center.

If these two documents are available, the inspection station employees do not have the right to refuse to issue a certificate. In a conflict situation, you should request a written refusal indicating the reasons.

Power steering device

We can say that the “seven” is equipped with the simplest type of power steering. It contains several basic elements that make it easier to control the car:

Hydraulic pump mechanism. It is through the cavities of the pump that an uninterrupted supply of working fluid is carried out and the necessary pressure is created.
Steering gearbox with distributor. This device is designed to ensure the passage of air flow. The air directs the oil in two directions: into the cylinder cavity or in the return direction - from the cylinder to the tank containing the working fluid.
Hydraulic cylinder. It is this mechanism that converts oil pressure into movements of the piston and rod, which reduces physical force when applying pressure to the steering wheel.
Working fluid (oil). Oil is necessary for the stable operation of the entire power steering system, since it not only transmits movement from the pump to the hydraulic cylinder, but also simultaneously lubricates all components. Oil is poured into a special container and supplied through high-pressure hoses.

Typical equipment of the VAZ 2107 implies two schemes for the operation of the hydraulic booster: transmission of movement to the steering rack or to the steering shaft.

Installation of power steering

The installation of the power steering kit must be carried out by an authorized service center, and the owner is issued a special document. The certificate of completed work is presented to the registration and examination department of the traffic police and is the basis for making changes to the PTS. During the operation, you should strictly adhere to the instructions included with the equipment.

The sequence of work to install power steering on a VAZ 2107 is as follows:

The car is driven onto a lift or inspection hole, the front part is suspended, and the wheels are removed.
Using special devices, the rod ends are detached from the steering wheel bipod.
Inside the car, the spline joint unwinds and the shaft on which the steering wheel is mounted is released.
The bolts securing the machine to the spar are released, after which the mechanism is removed and put away.
A new gearbox with an actuating hydraulic cylinder is installed in the vacant space.
A pump is mounted on a bracket on the engine cylinder block, providing the necessary oil pressure in the system. The drive belt is thrown over the crankshaft pulley and tensioned in accordance with the instructions.
The next step is the installation of pipelines, high-pressure hoses and their connection to the compressor and actuator.
The system is filled with operating fluid in an amount of about 1.8 liters and checked for tight connections.

Finally, the hydraulic circuit must be pumped, or rather, any remaining air must be removed from it. To do this, you need to turn the steering wheel until it stops in one direction and the other several times. After this, the first test run of the engine is carried out and the system is operational. Almost immediately after starting, the force on the steering wheel should decrease sharply.

Before further operation of the VAZ-2107 vehicle, the wheel alignment angles are checked on a special stand. If necessary, camber and toe indicators are adjusted to the values established in the technical documentation. It should be remembered that the power steering makes it easy to perform maneuvers at low speeds and turn the steering wheel even on the spot without much difficulty.

Is it possible to install a hydraulic booster on a VAZ 2107

If we talk about equipping the “seven” with a non-factory power steering, then we can consider this operation appropriate and even necessary.

The installation of power steering on a VAZ 2107 is dictated by the complexity of the vehicle’s management in various operating modes. Only with a booster does the quality of control and reliability of driving on uneven roads improve.

Thus, structurally, the “seven” of any year of manufacture is ready for installation work, however, it is recommended to turn to specialists for this service, since it will be extremely difficult to install the power steering mechanisms yourself.

You should also take into account the disadvantages that the driver of a VAZ 2107 will inevitably encounter after installing a power steering wheel:

high cost of the power steering kit;
installation work is problematic (you need to pay for the services of a professional);
the need for regular maintenance (checking the oil level, lubricant, etc.).

Installing power steering

If a motorist wants to install power steering on a VAZ-2107 with his own hands, which the manufacturer did not consider necessary to install in one of the most budget cars in the whole world, he can take one of two possible paths. Firstly, you can select the optimal steering rack that has power steering and then decide on its further location in the car. True, such an action will require enormous labor and money. Secondly, which is more expedient, you can buy a ready-made kit at an auto parts store that allows you to perform all possible most useful manipulations on the stationary steering rack.

Installing a hydraulic booster on a VAZ 2107

You should be very careful when choosing a power steering configuration. Thus, car enthusiasts on forums often write that factory hydraulic boosters from Lada Priora or Niva often jam, and during operation they require increased attention from the driver.

Therefore, it is more advisable not to chase new products from the domestic automobile industry, but to install standard power steering from the VAZ 2107. And since the “seven” is a rear-wheel drive car, the front suspension will use a mechanism with two pairs of transverse link elements at once. The entire steering system on the VAZ 2107, without equipping it with a hydraulic booster, consists of the following components:

steering gear;
three rods with steering tips;
pendulum;
swivel axles with rods.

Accordingly, in order to install power steering into this harmonious system, some modifications and upgrades will be required. The new power steering kit for the VAZ 2107 must include the following parts (you need to check their availability before purchasing):

Hydraulic pump complete with pulley.
Oil tank.
Gear mechanism.
Hydraulic cylinder.
High pressure hose kit.

To install the power steering on the “seven” yourself, you may need a set of open-end wrenches and removable devices, however, without extensive experience working with car structures, it is not recommended to perform this work.

Installation procedure for power steering

Traditionally, specialists in auto repair shops install a hydraulic power steering wheel according to the following scheme:

The car is securely fixed on a lift or on a pit.
The front wheels are removed, as they make access to the steering rack difficult.
Using special removable tools, the rod ends are disconnected from the bipod of the steering rack. In some cases, it will be necessary to use lubricant to separate rusted parts from each other.

After completing all of the above work, it will be necessary to bleed the hydraulic system and remove any air pockets from it. Pumping is performed as follows:

Turn the steering wheel sharply all the way, first in one direction, then in the other.
Perform turning inside out several times.
Start the power unit.
Almost immediately after turning on the engine, the force on the steering wheel will be significantly reduced. There should be no leaks in the hydraulic system.

Video: installation process

Before putting the car into operation after installing the power steering, it is imperative to check the installation angles of the front wheelset. This work is performed by a specialist at a special stand. If necessary, you need to do a wheel alignment.

Steering device

The “Seven” belongs to the category of rear-wheel drive cars; the front suspension uses a layout with two pairs of wishbones. The steering of the vehicle in the standard configuration without power steering consists of the following components and mechanisms:

systems of three rods with tips;
steering engine;
pendulum;
rotary axles with rods.

The steering gear has a gearbox with a worm gear; its bipod is connected to a similar part of the pendulum by an intermediate rod. It ensures simultaneous rotation of both nodes at a certain angle. The external rods, which transmit force to the wheel axles, consist of two parts. With their help, the toe angle of the front wheels is set.

Electric booster for VAZ 2107

An easier way to make the 7 easy to drive is to install electric power steering. Structurally, the VAZ 2107 is ready for such a procedure; moreover, due to the absence of oil containers, installation will be easier and faster.

The electric power steering wheel copes well with loads; in terms of operating efficiency, it is practically no different from the effectiveness of hydraulic power steering. At the same time, the electric mechanism does not require maintenance or constant monitoring.

The most affordable version of the EUR for the VAZ 2107 is the “Aviaagregat” mechanism from a domestic manufacturer. The mounting location for this device is the location of the standard steering column. The design of the electric amplifier includes a relatively small number of parts:

the amplifier itself;
bracket for its fixation;
intermediate value cardan;
casing, wiring and fastening elements.

In terms of cost, the EUR is inferior to the power steering, so VAZ 2107 owners often prefer to install “electrics” rather than “hydraulics”.

Video: EUR on a “classic”

The power steering wheel is a completely common element for modern car models. However, the standard equipment of the VAZ 2107 did not provide for such a configuration; the owners have to “fight” this drawback on their own. Due to the high risk of errors in installation and connection, installation work is recommended to be carried out only in a car service center.

Installation of EUR on VAZ 2107

Before starting work, it is necessary to remove the terminals from the battery to avoid a possible short circuit.

The procedure for installing the EUR is as follows:

remove the cover from the steering wheel;
dismantle the old steering cardan and install a new one, included with the EUR;
drill holes for mounting the EUR according to the diagram given in the instructions;
secure the EUR mechanism;
connect the wires from the revolution and speed sensors;
connect the EUR power supply wires through the fuse;
install protective cover
connect the terminals to the battery.

I looked up to the pedal from the pipe. Pokemon are cross-armed. Sawing a stunted cooling fan with a casing for steam, smiled. Look at the little things in general, you should also hang power clamps on the brake hoses. The very fact that you do such work is well done, but there is no qualification at all. And with regards to cold starting - the starting mechanism (choke) must be cocked on a cold engine, 20 degrees is a cold engine. Gain experience. There are installation nuances, but you really froze where you could have gotten out of the situation differently.

If you have ideas, implement them on your car) and the pedal made from a pipe turned out to be extremely reliable) at first we tried to bend the factory pedal to make it more beautiful, but it began to burst, so in the absence of a laser cutting machine, a bending machine and a lot of time, we came up with the situation this way . Regarding the casing, what suggestions do you have? I'll be happy to listen. The fan was cut 2 mm where it contacts the belt, the rigidity was not affected)

Wonderful video, now I definitely understand that this option is not an option for me at all. Thank you very much!

Well done guys! Good experience, interesting content!

Thank you) or there will be more))

Hey guys, how much will it cost if you put a van on a VAZ 2104, all the spare parts and work, in general, the whole amount, the same power steering, tell me the price in advance, thank you in advance

Gur kit about 55, work 25

50k + work is certainly interesting when the whole car costs 60)

@Dmitry Ponomarev I understand, I didn’t take into account the dependence of price on location. So you need to take yours to St. Petersburg for sale)

@Pavel Sidorenko she is about 86 years old, in St. Petersburg the prices for standard classics are merciless)

@Dmitry Ponomarev, it’s strange that I was in this condition in 91gv with a summer mileage of 89 thousand for 60 where do you get such prices for a Lada.

I agree, even for 260 you won’t buy it)

You can't buy it in this condition for 60k

What city do you work in?

Guy, thanks for the detailed video) I’ve already watched millions of videos on this topic, but here everything is so chewed up)) everything is detailed and clear, even without the process itself. But I would like a little more detail about attaching the pulley to the knee) is there an original nut left or is it from an injection engine with an additional spacer? I will soon install it in the original Niva 2121. In addition to the pleasant rotation of the steering wheel, it also adds some reliability to the unit) new steering gears last an average of a year and simply fall apart in the literal sense. I’ve already replaced several of them.. all because the factory doesn’t produce them, they are made very handicraft.. hence the quality.. and Gur is now at the factory)

@kuka isaev they sell it here)) in alsport)

@Dmitry Ponomarev together with sewing and where do they sell it? thanks for the answer.

@kuka isaev the set is about 50,000 with everything new

so is it from the field? and how much does it cost?

The nut is already there with a spacer, there are also enough left nuts, especially not worth taking from the bulkhead)

Wow great video! In what city did I find this kit?

We ordered it ourselves from Tolyatti) we also sell spare parts)

Well done ! I will also install a VAZ 2106 Gur. I only assembled the gear and components myself, and why didn’t they install a coil? cooling? about the vacuum cleaner I will install from shnivy. I will also post it on the channel soon. Good luck

50,000 set, for work it usually looks like the condition of the car

How much did it cost?

As practice has shown, the liquid does not get very hot on this pump and machine

So. It is possible that another six will arrive at Alsport. (shut up and take my money.)

five for the craft)) but in general... you can’t decorate a pig with lipstick. It won't get any better.

This is more for connoisseurs, I myself don’t like classics (I’m too tall for them), but it gives me respect when people keep them in this condition, as far as I understand, this six is some kind of rare transitional, therefore quite a valuable specimen)

Dmitry is great. In 2003, I had a Shoha, I installed 185 R13 tires and it was quite difficult to turn the steering wheel while still standing (on the move without any problems). With hydrach it is very convenient to park in narrow spaces, even for girls. Respect, fine work.
